What is Cardiology?
Cardiology is the specialty within medicine that looks at the heart and blood vessels. Your heart consists of four chambers, which are responsible for pumping blood to your lungs and then the rest of your body. The study of the heart includes the heart muscle (the myocardium), the valves within the heart between the chambers, the blood vessels that supply blood (and hence oxygen and nutrients) to the heart muscle, and the electrical system of the heart which is what controls the heart rate.
Your GP will refer you to one of our clinics if they are concerned about your heart and want a specialist opinion. The referral is prioritised depending on urgency with waiting times of 2 weeks to 4 months.
You may be sent a questionnaire prior to your clinic visit to assist us with making a diagnosis and determining if any tests need to be done prior to you seeing a specialist.
